Case 4: The Mid-ventricular Short Axis View in a Normal Volunteer (Back to Indications for Cardiovascular MRI)
Double oblique imaging plane: Anterior chest wall on image left, back toward lower right, head toward upper right. See Case 5 for orientation to structures. This view is convenient for qualitative assessment of regional wall motion abnormalities.
Three distinct MRI acquisitions are compared in these three examples. At left, is a conventional, segmented gradient echo cine loop acquired in a 16 heartbeat breathhold (FGRE). In the middle is a hybrid segmented gradient echo cine loop accelerated by short echoplanar readouts (FGRE-ET). At right is the same individual studied using a research pulse sequence called True FISP. The advantages of each method are listed below each image.
